SPECIFICATION forming part of Letters Patent No. 314AlG, dated March 24, 1.885.

Application tiled May 3l, 1884. (Nomollel.)

To all whom it may concern,.-

Be it known that I, GEORGE H. Binocoli, of Plainfield, in the county of Union and State of N ew Jersey, have made an invention of cer- 5 tain new and useful Improvements in the Construction of Steam-Boilers; and I do hereby declare that the following is' a full, clear, and exact description and specification ofthe same.

As my invention is especially applicable to IO the class of sectional water-tube boilers, I have shown and will proceed to describe it in connection with one of the well-known forms of such boiler exhibited in its other main features by several patents heretofore granted to I5 Babcock and VilcoX.

The object of my device is to gain strength and elasticity for the boiler, convenience in its transportation and erection, cheapness in construction and repair, and efficiency and 2Q reliability in its operation.

In the drawings, Figure 1 is a side elevation (setting sectional) of a boiler embodying` my improved construction. Figs. 2, 3, and 4: show details of construction and connection.

The boiler shown by Fig. l as exhibiting my invention in the best practical form in which l have as yet embodied it is a sectional water-tube boiler having inclined tubes G, expanded into headers A A, which are in turn 3o united to a steam and water drum, B, at a higher level by suitable connections,E and F.

D is the furnace, and when re is started therein circulation commences in the boiler in the usual and well-known manner. Flamebridges g compel the hot products of combustion to pass in a tortuous course around and between the tubes to their outlet, and a muddrum, C, at the lowest point of said boiler receives and retains the deposit of sediment,

4o and has ot' course suitable provision for the convenient removal ot the same.

The essential part of my invention relates to the construction of the headers A A, which in most boilers of this pattern have been formed in sections running vertically the entirelength of the tubes, or have been so joined by vertical connections as in practice to form a continuous vertical or but slightlyinclined pipe, but while preferably (though not neces sarily) following the sinuous shape to give a staggered arrangement to the tubes, Fig. 4, I form these headers in short vertical sections adapted, as shown, to respectively overlap each other, and to be conveniently nippled or in any way connected together (as at points ct a) in line with their respective upper and lower tubes-z'. e., at right angles with the vertical connection above referred to. By this arrangement and construction any required number of sections can be conveniently used, 6o horizontal space `is economized, the alternate connection and the shorter header obviously increase both strength and elasticity, the tubes connected with the headers and the headers with each other and with their steam and mud- 5 drum connections by the cheap and. effective method ot' expanding, and each tube thereafter reached without diiiiculty directly for cleaning and repairs through the ordinary hand-holes. Finally, the improved header is not only more easily made and conveniently handled and transported, but in case of damage or accident through carelessness or ill usage it-s repair `or replacement will be both easier and cheaper.

Alternative methods ofconnection are shown by Figs. 2 and 3; but I do not conline myselt' to any method ot` connection or to any number ot sections or proportion ot' tubes to each.

I claim as my inventionl. In a sectional boiler, the overlapping headers communicating with each other, substantially as shown and described.

2. In a sectional boiler, the combination of overlapping headers with a steam and water reservoir, substantially as described.

3. In a sectional steam-generator, the combination ot' overlapping headers with a muddrum communicating with the same, su bstantially as shown a'nd described.
